The Relationship Between Education and Adult Mortality in the United States
利用美国人口普查数据，以1915-1939年义务教育法为工具变量，发现教育对死亡率有因果影响，且效应可能大于以往估计。
Prior research has uncovered a large and positive correlation between education and health. This paper examines whether education has a causal impact on health. I follow synthetic cohorts using successive U.S. censuses to estimate the impact of educational attainment on mortality rates. I use compulsory education laws from 1915 to 1939 as instruments for education. The results suggest that education has a causal impact on mortality, and that this effect is perhaps larger than has been previously estimated in the literature. Copyright 2005, Wiley-Blackwell.
